Exec () Creating two different process for FFMPEG

Posted by: admin September 25, 2018 Leave a comment

Questions:

I run this command in exec () and it creates two FFMPEG processes one at the same time as the other but with different PID. Is this behavior normal? When I run the code directly in the shell this does not happen.

$ffmpeg = "/home/user/bin/ffmpeg -hide_banner -loglevel verbose -n -i https://sitelink/list.m3u8 -map 0:4 -map 0:5 -acodec copy -bsf:a aac_adtstoasc -vcodec copy video.mp4 1> log.txt  2>&1";

    exec($ffmpeg, $output, $var);

Example of the two processes created
